90 days — 'Waltham 29' broccoli was bred to withstand the increasing cold of fall and therefore is not the best choice for early spring planting. If sown too early in the summer, the center heads may flower prematurely. In most circumstances, it is best to time your planting for late summer, fall, or even winter harvests. The plants are compact with large crops of side shoots and solid medium green heads. Make sure to keep up with harvesting to maximize your total yield of shoots. It reportedly can survive dry spells.
